That's fun to watch, but I think it would get old (though maybe he was nudging during that video?). Love the concept though.
I think they should ease up on the coil strength / switch sensitivity, so it doesn't stay in the bumper as long, unless that video represents an unusual amount of bumper action. Actually, just switching to black rubber there might help, so it didn't keep bouncing up. I feel like those switches are going to take a real beating.
